VEHICLE-TIRE Specification of Letters Patent.

Patented Oct. 27', 1908.

Application led September 12, 1907. Serial No. 392,478.

To all whom it may concern:

Be it known that I, FREADRICK A. STALL, J r., a citizen of the UnitedStates, residing at Darlington, in the county of Darlington and State ofSouth Carolina, have invented certain new and useful Improvements inVehicle-Tires, of which the following is a specification.

This invention relates to certain new and useful improvements in vehicletires.

Rubber tires for ordinary vehicles, such as carriages, buggies, lightwagons, automobiles, etc. are now in general use, the preferredstructure being a rubber tire having a wire passed longitudinallytherethrough to secure the same in position upon the periphery of thewheel. This tire, when in use is subject to considerable lateral strainand vibration which causes the round wire which secures the same inposition, to work right through to the periphery of the wheel, thuspermitting the tire to stretch and eventually drop off, and alsoallowing the same to roll under the lateral strain.

My invention has for its object the production of a tire and means forsecuring the same in position, which are so constructed as topractically overcome this cutting effect of the Wires, and to providemeans whereby the tire is securely fastened in position in such manneras to afford a maximum resistance to the rolling action of the lateralstrain.

A further object is to secure the tire in such position on the vehiclewheel as to secure a maximum bearing surface.

The invention will be hereinafter fully set forth and particularlypointed out in the claim.

In the accompanying drawing z-Figures 1 and 2 are cross sectional viewsof two different forms of vehicle tires embodying my invention. Fig. 3is a sectional view of one of said forms with the securing wire removed.Fig. 4 is a detail view of the wire.

Referring to the drawing, 10, 11, designate two different forms oftires, the tire 10 being provided with a single longitudinal opening 12arranged approximately two thirds of the distance from the ti or treadthereof. The tire 11 is provided with two holes 1.3 near the bottomthereof. Each of the holes or openings 12, 13 is formed with a bottomwall which is flattened at 14 said bottom wall joining the top or archedportion of the holes or openings by slightly inclined faces 15. Thesecuring wires 16 are each provided with a flattened face 17 arranged tobear upon the bottom wall 1.4, said wire serving to secure the tire inposition in the usual and well known manner.

In practice, the flattened bottom portion of the hole or opening in thetire, and the flattened contact face of the wire, provide va maximumbearing surface, whereby the wire will rigidly secure the tire in.position and prevent lateral movement thereof while in use. Thefiattened bearing surface also prevents the wire from working downthrough the rubber of which the ltire is usually cornposed, and therebyprovides an efficient means to prevent stretching of the tire. At thesame time, it will be observed that by forming the holes or openingswith the slightly inclined faces adjacent the bottom wall, the wire isprevented from cutting through the tire as the latter tends to rollunder the lateral strain.

I claim as my invention The combination with a vehicle wheel, of aresilient tire provided with a longitudinal bore having a flattenedunbroken bottom face, an arched top face, and upwardly diverging sidewalls connecting said top and bottom faces, and an approximatelyTcylindrical securing wire threaded through said bore and provided with asmooth, unbroken flattened ottom face contacting with the bottom face ofsaid bore.

In testimony whereof I affix my signature, in presence of two Witnesses.
